SPECIFICATION forming part of Letters Patent No. 292,441, dated January.2 2, 1884.

Application filed November 8, 1883. (No model.)

To all whom it may-concern..-

Be it known that I, THOMAS MAXON, a citizen of the United States,.residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Wagon-Jacks, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

My invention relates to lifting-jacks to be used in lifting the axles oflight vehicles for such purposes as may be necessary.

My object is to make a comparatively light implement, which shall at thesame time be durable and efficientand quickly operated.

To enable those skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

In the accompanying drawings, making part of this specification, Figure1 represents a side elevation, with one side of the frame removed. Fig.2 is a cross-section taken through the line a: x.

A represents in the drawings only one half of theframe of the jack. Thepedestal of this frame is bolted to any suitable base, B representing abase.

H, represents a bracket purpose of which will be described hereinafter.

f and-3y are ears, through which bolts are intended to pass to securethe two parts of the frame together.

a: is another ear on the frame, which carries a pin that works in aloop, to be described, to act as a guide. w

0 represents a sliding bar, which plays up and down between the twoparts of the frame in a suitable recess madeto receive it. This bar uponthe frame, the

is provided on one side with a bracket, the small bar a being'thelowerand main support. I; and c are steps upon the bracket to enable the jackto be accommodated to axles of different heights.

2' represents a portion of the bracket, which runs parallel to the bar0, leaving a vertical opening, d,'between the two. The pin a on ear w ofthe frame'plays in this opening and acts as a guide for the bar 0. I

I represents a lever, which is provided with a wheel, J, at an elbow init, and which is pivoted to the bar 0 at m. The wheel J rests and playsupon the bracket H of the frame. The bar 0 is raised and lowered by thislever I, and/when the bar is at its highest capacity the pivot of thewheel J rests under the pivot m, and thus the bar with its burden issustained until it is desirable to change it. The

top 6 of the bar is the highest of the lifting bar 0, having its bracketwith steps and guideopening (I, and the operatinglever I, with wheel J,the several parts being constructed and operating as and for the purposeset forth.

In testimony whereof I aflix my signature in presence of two witnesses.

THOMAS MAXON.
